No, I'm relying on the auto setting.
Maybe a proper setting will remove the margins?
I made some changes with the latest commits that do try to eliminate the black margins in many resolutions but unfortunately, you can't get a perfect result where you have both integer scaling and the border exactly filling the screen with a 1024x768 monitor as the pixel ratios don't match up.

Really good picture but so far can only get limited colours on the second palette (image attached), not sure why at this point but I wonder about a dry joint somewhere. RV2 doesn't seem to do much, but the sync seems rock solid whatever. Anyway just had to post success!
I saw the same so I ordered from eBay and paid about 2-3 times the value including postage. Not ideal but better than 4x.
